This study shows that AHK3 and CKX4 in roots regulate tZ-type cytokinin transport via xylem, affecting leaf size based on nitrogen availability.

This study shows shoot nitrate status regulates Arabidopsis growth and gene expression via shoot IPT3, which modulates CKs and transcriptomic responses in shoots and roots.

This study shows that Arabidopsis RFNR1 and RFNR2 are essential for root growth and ferredoxin-dependent processes, as demonstrated by mutant analysis and transcriptome changes.

The paper shows that STOP1 dominates Arabidopsis ammonium tolerance over NRT1.1, with STOP1 directly activating NRT1.1 transcription and regulating common target genes.

This study shows that alternative oxidase (AOX) reduces mitochondrial oxidative stress and supports plant growth under limited nitrate reduction in Arabidopsis thaliana.
